[comp.sys.sun] Laser Printer for a Small Network of Suns?

peters@cc.msstate.edu (Frank W. Peters) (05/15/89)

Hello,

We are in the very first stages of purchasing a laser printer to serve a
small network of suns (3/160 serving 7 3/50s three of which would be using
the printer on a regular basis).  I'd like to hear people's opinions of
the issues involved and evaluations of various printers.  We'd also like
to hear what software exists to help support such devices (I've heard
mention of a package called transcript?).

Thanks

Two options:  
	a.  you're willing and experienced enuf to futz with 3rd party
	products
	b.	you'd rather not spend the time/energy/etc. 

If a., then you can look at things like the NEC LC-890 or Qume (look for
absolutely the best price for a printer that understands postscript and
works off serial).  And then buy something like devps from Thalatta or
Elan (from wherever) and install it.

If b., then buy the SunApple machine with Transcript.  No futzing
necessary.

I went route a. and after almost a year of futzing with NEC, weird line
levels, buffer (parallel/serial convertor) boxes and no transcript-clone
software, I think that if I had it to do all over again, I would have gone
route b.

We have an Apple LaserWriter, an Imagen 24/300, and an HP LaserJet
2686A.

The Imagen is a very old model.  They admit to having a lot of problems
with it and claim that the new ones are much better, but I can't vouch for
that.  The Imagen uses a language called Impress for which we have
software supplied by Imagen which includes everything you need to use the
printer on a Sun, including the printcap entry.  They have newer printers
which also understand postscript.  We don't really know how to use Impress
and don't have any software that lets us do anything sophisticated with
it.  We can just print ASCII files in portrait, landscape, or landscape
with two columns.  The only reason we use this printer is because it is
faster than any of the desk top printers (the Imagen stands on the floor).

The LaserWriter was purchased from Sun as a "Sun LaserWriter", but it's
really an Apple with a Sun logo pasted on.  The LaserWriter speaks
postscript and we got the transcript package for it from Sun.  Transcript
includes everything you need to use the LaserWriter, or any other
postscript printer (or at least, that's what I would assume to be the
case; I haven't yet tried to use it with another postscript printer),
including the printcap entry.  It also comes with a set of front end
programs for converting various types of files (ASCII, Sun rasterfiles,
troff, etc.) into postscript, with various options (different fonts,
sizes, orientations, title blocks, image scaling, etc.).

Sun does not support the HP LaserJet, but I was able to write all of the
software we needed for it myself.  And Sun was very helpful even though
they don't officially support it.  I asked Sun a question about getting
the handshaking to work and they sent me a printcap entry and rasterfile
filter that were submitted by another user.

The only advantage of the HP is that it's cheap.  Its major disadvantages
are that it can't print in any combination of font, size, and orientation
(only those that are supported by your font cartridge), it has limited
memory, so it can't print high resolution rasterfiles, it has no graphics
capabilities other than bitmap printing, it doesn't run postscript which
makes it impossible to use all of the neat postscript stuff that gets
posted to the net all the time.  and it's next to impossible to mix
graphics and text.  The HP series II has more memory, but I don't know
whether that makes much of a difference since I haven't yet tried to use a
series II with the Sun.  The LaserWriter has none of these problems.

Sounds like you've got the original LaserJet, which was indeed pretty
dumb.  It is still possible to do typesetting on it if you go very easy on
the fonts; there is nothing hard about mixing text and graphics, and
missing characters can be drawn in by suitable software.  The later
models, starting with the now-obsolete LaserJet Plus and including (I
think) all current ones, have more memory, downloadable fonts, and
somewhat improved graphics, and are generally better.  They are arguably
superior to PostScript machines for bulk text printing, because the
speed/dollar ratio is much better -- PostScript is hard to interpret
quickly without spending a lot on hardware.  We've used them for years and
are very happy with them.  You do need suitable software; they trade off
hardware smarts for cost, and so the host has to supply the intelligence.

If you are doing serious graphics or are prone to the "ransom note" style
of typography, however, you definitely want a PostScript printer.  We now
have one of those too.

Yeah.  PostScript is necessary here and there.  If you're using different
fonts of the same typeface, say.  Or perhaps EVEN, yes, using more than
one typeface, or, making the face fit the the job, kerning with care,
trying to communicate with emphasis and clarity .. that is to say, where
one is concerned about GOOD Typography.

So to say, when your ransome notes are IMPORTANT for you.

Nonsense.  A LaserJet Plus will put any character you want anywhere you
want it.  In different fonts of the same typeface, in multiple typefaces,
with well-chosen faces, kerned, emphasized, and clearly.  Your software
has to supply the characters, and tell the printer exactly what to do --
as I said, there's a tradeoff involved -- but the printer will do it.  You
run into limitations when you're trying to use lots of different fonts
(i.e. the Macintosh "ransom note" style, changing fonts with wild abandon
and no concern for how ugly the result looks), and the less said about
graphics the better, but for typesetting normal text it works fine.

It's amazing how many people think that typesetting began with PostScript.

And what kind of software does this?  Is it your assembly code?  Does it
resemble the proprietary coding that used to drive Xenotron, Monotype,
Linotron, Compugraphic typesetters?  (All of whom now offer PostScript.)
How many applications on the Sun drive the LaserJet this well?  What's the
language?

PostScript has goosed the old time typesetting industry into using modern
computing practices.  PostScript is portable, has tons of applications on
many platforms using it as output, and does graphics.  BTW, Graphics!

A PostScript printer will therefore continue be useful in the future,
since it prints / proofs the standard page description language.  You can
save money on laser printers, but I wouldn't buy one that can't interpret
PostScript.  Unless I have one really dear HP laserjet application.

The software is any of several freely-redistributable back ends for major
text formatters like ditroff and TeX.  Written in C, portable, completely
non-proprietary, suitable to driving dozens of different laser printers
that are LaserJet-compatible (rather more than are PostScript compatible,
at present, I think).  Text formatters are the major issue here, since --
as I mentioned -- one would *not* pick a LaserJet for graphics.

I will freely concede that PostScript is the wave of the future for
talking to output devices, and is to be preferred if other things are
equal.  At the moment, they aren't, as LaserJets are cheaper and usually
faster.  For people who have major need for graphics or portable output,
this is not significant.  Those people are a minority at present.

I also note that we have quietly changed the subject, away from claiming
that the LaserJet can't do the original job of printing text nicely.

We also never mentioned `Transcript' once, so I suppose we are to be
congratulated.  I guess you might be right about people that need graphics
or portable output being in the minority (I have no statistics), but if
true, I think that is rapidly changing.  

I think that people _now_ setting up a "small network of Suns" are
probably thinking about WYSIWYG software like FrameMaker or it's
competitors, (the Interleaf products and The Publisher are competitors,
troff-derived products like SoftQuad's are not), all of which rely on
PostScript printers (note this applies to The Publisher, although TeX
derived.)  This makes them, willy nilly, need graphics & PostScript
portability. 

I will totally agree that PostScript printers are overpriced (until Adobe
gets some competition for its controllers), and one ought to look at, or
hope for, alternatives.  I've heard in the interim about adding a
PostScript module onto the LaserJet, and also from a company that has a
software driver for it that accepts PostScript, so maybe it's not a bad
choice anyhow.

I think also, if you follow the `fonts wars', you'll know that far more
fonts are available with PostScript (nowadays you can get some really keen
`official' Compugraphic/Adobe fonts), than with any alternative (I know, I
know, not many people care about type that much, yet) - and the really
interesting thread developing is, _whose_ PostScript (Adobe's? Apple's?
Sun's?), and whose _fonts_.  Sun MAY be able to outdo Adobe with regards
to the number and quality of fonts to choose from, if they're on their
toes.  Of course nobody except Apple (other than the smaller `Bitstream'
cloners) has admitted to developing a printer controller.
